Ernst Von Salomon said this quote

Certain directors and actors were constantly preoccupied by one problem, and apparently, one only. This was connected with the so-called German greeting, which was the method of hailing a friend by raising the right arm straight out with the hand extended at, or slightly above, the level of the shoulder. This greeting had very definite political implications; it was employed daily by millions; and the directors and actors saw no reason why it should not be one on the films in a simple and life-like fashion. They failed. Even when shown in the rushes the effect on the select and professional audience was simply to produce uncontrollable hilarity. The cinema can do a great deal. It can entrance, t can tell fairy tales, it can be realistic or surrealistic -- but it cannot portray a gesture that is false without underlining the most brutal way its basic falseness. The German cinema could not reproduce the German greeting; it was the greeting that was to blame, not the cinema.
